Fantastic to see someone else relying on data instead of feel and assumption

I saw similar low oil pressure yesterday during straight line braking at the track. Engine was at medium oil level so this is frightening......IF it is even a problem?

Today on the street after getting a little bit of heat in the Cup2s I could also provoke ~25psi from hard braking. I added 0.5 liter - and again ~25psi... The stupid iDrive measured no difference in oil level after the first 0.5 so I added another 0.5. Guess what? I can still provoke low oil pressure Seems for me it is just the braking part, no need to add lateral force. Oh, and I have NO CLUE how much oil is in the engine really

Where are you now with your car? What route did you take?
